The flexible rubber joint buried protection device, with sufficient space around it, will not affect the displacement performance of the rubber joint, but also can isolate the rubber joint from the external filling, and also make the pipeline slide freely at both ends of the device without generating In case of any resistance, after the pipeline is installed, the backfilled ground is still smooth as before, and the vehicle stacking heavy objects or installing equipment will not be affected.
This underground device is a combination of two semi-circular hollows. The rubber joints and pipe flat welding flanges are all installed in the body. Two semi-circular small flat steel strips are provided at both ends to ride on the outer pipe walls of the flanges on both sides. , The support of the standing surface at both ends is determined according to the depth of the soil layer, enough to bear the external pressure load.
The device is equipped with a certain number of locking bolts for assembly after installation. The installation method is: install the rubber joint → apply asphalt anti-rust paint inside the protection device → install the lower 1/2 protection device → put on the upper 1/2 protection device → tighten the locking bolts (note that the rubber joint should be installed during installation) Ensure that it is in the center of the device → coat the protective device with asphalt anti-corrosion paint → backfill the original soil, tamping the lower part, and solid the upper part → three-in-one and cushion layer → paving the ground (it is better to have a permanent mark in the appropriate position for future Confirm the location when checking and replacing).
Special attention: Be sure to provide the deep buried layer when ordering, so that we can set up a reasonable protection device for you. The protection device can be used for more than 30 years as long as the surface anti-corrosion treatment is done during installation.
